SANITARY CLOSET.

SPECIFICATION forming part of Letters Patent No. 584,425, dated June 15, 1897.

Application filed November 18, 1896. Serial No. 612,546. (No model.)

To (0Z5 whom it may concern;

Be it known that I, THOMAS F. STRAOHAN, J r.,acitizen of the United States, residing at the city of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Sanitary Closets,

of which the following is a full, clear, and

exact description.

My invention relates more particularly to that class of sanitary closets which are substantially combination sanitary closets and urinals and which are flushed either directly through a spring-valve or through a tank.

Referring to the drawings herewith, consisting of one sheet, in which like letters refer to like parts, Figure I is an elevation of the closet, showing my invention. Fig. II is a similar view showing said closet as a urinal. Fig. III is a detailed vertical cross-section of my spring-plunger mechanism hereinafter more fully described.

A is a closet of any desired form.

B is a flush-valve, the pressure-stem being shown at b.

O is the seat to thecloset, which is hinged thereto at c.

E is a treadle or leverarm, which is pivoted to the post F, which is in turn secured either to the floor or to the adjacent wall.

D is a levei arm secured to the seat 0 and connected with the treadle E by means of the rod G and the tubular rod g, said rod G and said tubular rod 9 being adj ustably connected by means of the set-screw d. The pivotal point of connection between said lever-arm D and said rod G is at a point slightly above the pivotal point of the hinge c, as shown in the drawings, so that when the seat 0 is raised, as shown in Fig. II, the pivotalpoint of the lever-arm D will be without the vertical line of the pivotal point of the hinge 0, so that the seat 0 may be returned to place, as hereinafter shown.

H is a connecting-rod secured at its upper end to the stem of the valve 1) and connected through the cylinder I and the lug J with the treadle E. Upon the lower end of the rod H (see Fig. III) is a piston-head h, to which is secured an extension-spring K, which at its lower end is in turn secured to the lug J. The upper end of the cylinder I is closed by means of an adjustable packing-ring held in place by the set-screw e and which is provided with a small vent or opening 2'. The lug J is also adjustable within the cylinder I by means of the set-screw f.

In operation, when the closet is used as a closet, the normal pressure brought to bear upon the seat 0 presses down the stem 11 and flushes the closet. When used as a urinal, the treadle is forced downward from the position shown in Fig. I to that shown in Fig. II. The seat (I is raised by means of the lever-arm D, and the connecting-rods joining it with the treadle E. The spring K within the cylinder I is extended, thus drawing the rod I-I downward and by pressure upon the stem Z) flushes the closet. The action of throwing the treadle downward and raising the seat is rendered gradual by reason of the slow expulsion of the air within the cylinder I through the vent i. WVhen the foot is removed from the treadle, the spring draws it upward and the plunger h descends gradually as the air is admitted to the cylinder through the vent '5, thus closing the valve B and gently returning the seat 0 to place, as shown in Fig. I.

It is apparent that the position of the spring K may be changed so as to act as a compression-spring engaging against the packingring and the piston-head without departing from the spirit of my invention.

As the closets differ in height it is necessary that the mechanism be made adjustable, and therefore the connecting elements I and J and G and g are adjustable through the setscrews f and d, respectively, and it will be seen that the closet shown in Fig. II is somewhereby the seat is raised and thecloset flushed simultaneously, and whereby the valve is closed and the seat returned to place simultaneously, and Without shock to the valve or slamming of the seat, substantially as set forth.

In testimony that I claim the invention above set forth I aflix my signature in pres ence of two Witnesses.
